Why dont my meshes light up from the point light?
Author
Im using the directx 9 sdk meshes tutorial to load meshes and draw them. Then i get a point light in there with them, but the point light only lights up my vertices on which i set the normals and materials for.
How can i get the meshes to light up awell?
For a mesh to recieve lighting it NEEDS to have normals. And for the lighting to make sense, you NEED to set a valid material.
So add normals to the meshes that don''t have them.

how would i go about that?
Heres 2 functions that i use to load and draw meshes.
load mesh
draw mesh

load mesh

void DrawMesh(int index=0, int keyFrame =-1) { for( DWORD i=0; i<myNumMaterials[index]; i++ ) { myDevice->SetMaterial( &myMeshMaterials[index][i] ); myDevice->SetTexture( 0, myMeshTextures[index][i] ); myMesh[index]->DrawSubset( i ); } }This topic is closed to new replies.
